What Size Pressure Washer for 2 Story House

Read on for our guide on what size pressure washer for 2 story house so you do not waste your money!

What size pressure washer for 2 story house?

When people talk about size for a pressure washer, they do not mean small, medium, or large. What they are talking about is the pressure output of the pressure washer. The power is expressed in PSI or pounds per square inch. You will also see some products that indicate gallons per minute or GPM.

So, what size pressure washer for 2 story house must you buy? My recommendation is to get a heavy-duty pressure washer that is capable of delivering at least 2800 PSI or pounds per square inch. I also suggest that you get a product that releases at least 2.5 gallons per minute.

If you can find one that uses 4 gallons per minute or 4 GPM, then it is a better option. However, it may be more expensive. There are also products that offer at least 3,000 PSI. If you see these machines and they fit your budget, get them.

Why pressure wash a 2 story house?

Cleaning the sides of a 2 story house manually is a laborious task. With a pressure washer, you can save time and effort.

Pressure washers make use of high-pressure water to remove dirt, dust, mold, grime, spiderwebs, and much more, in just a small fraction of the time spent cleaning by hand.

Should you use an electric or gas pressure washer to clean a 2 story house?

The better option is the gas-powered pressure washer. They have more power and are easier to operate. They are tougher than electric models.

Gas-powered pressure washers are made for heavy-duty use. Because they have such power, they can remove gums and even tree saps that have already dried. If you will use it for removing paint, a gas-powered pressure washer is also much more reliable.

However, gas-powered pressure washers are huge—and they are noisy. I am not saying that you cannot use an electric pressure washer for a 2 story house. You can do this, but you will have problems later on with the performance.  

The only gripe you will have with gas-powered pressure washers is the noise. Sadly, there is no technology yet by which engines can keep really quiet. Despite this, there are many gas-power pressure washers that will not make you deaf—they are noisy but quiet enough not to damage your ears.
